A rare vintage of Stanislaw Augustus thalers.
In the early 1780s, the mint significantly reduced the issuance of thalers, and their mintage did not exceed 10,000 pieces. This was until 1783, when, with the change in the type of royal portrait (to a bust without a ribbon), the issue volume of this valuable denomination was incurred.
The yearbook was most likely struck with a single pair of stamps.
